GM is canceling the planned production of an advanced DOHC V-8 gasoline engine due to go into production in 2009 that it would have applied to luxury vehicles—cars or trucks.
The company announced last year that it planned to invest $300 million into the Tonawanda plant in New York for renovation to part of the plant, new machinery and tooling to support production of the new gasoline V-8.
The planned production of a new 4.5L V-8 Duramax turbo-diesel, also slated for Tonawanda in 2009, is still a go. (Earlier post.) The new diesel improves engine fuel efficiency by 25% compared to gasoline engines, reduces CO2 emissions by 13% and cuts particulates and NOx emissions by at least 90% compared to comparable diesels today, according to GM. The engine will be rated in excess of 310 hp (231 kW) and 520 lb-ft (705 Nm) of torque.
This will be GM’s first engine to use a selective catalytic reduction NOx aftertreatment system with a diesel particulate filter to help achieve the Tier 2 Bin 5 and California LEV 2 emissions standards. The engine will be applied in pickup trucks of less than 8,600 lbs (3,900 kg) GVW and the HUMMER H2 after 2009.
GM will invest $100 million in the Tonawanda plant to support production of the new diesel V-8.
The GM Powertrain Tonawanda engine plant currently produces the 4-cylinder, Ecotec 2.2-liter engines for the Chevrolet Cobalt, HHR and Malibu and the Saturn Ion; High Value, V-6 3.5- and 3.9-liter engines for the Chevrolet Impala and Monte Carlo, and the Pontiac G6; Inline 4- and 5-cylinder engines for the Chevrolet Colorado, GMC Canyon and the Hummer H3; Vortec 8100 8.1-liter engines for the Chevrolet Kodiak, GMC TopKick and sold outside GM for various marine applications.
